Available to US bidders only. Very rare Challenger-flown LRSI (Low-temperature Reusable Surface Insulation) tile, 6 x 6.5, #V070-391039 037-008451. Tile was flown on the first six flights of Challenger: STS-6 (maiden voyage), STS-7, 8, 41-B, 41-C, and 41-G, before being replaced. Accompanied by its Flown Hardware tag, filled in by a technician, “Orbiter No. 099, STS Number 17,” (referring to its 17th processing flow), dated November 13, 1984. These tiles would cover the upper wing near the leading edge. They are also used in selected areas of the forward, mid, and aft fuselage, vertical tail, and the OMS/RCS pods. These tiles protect areas where reentry temperatures are below 1,200 °F. The white color is by design and helps to manage heat in orbit when the orbiter is exposed to direct sunlight. These tiles are reusable for up to 100 missions with refurbishment (100 missions is also the design lifetime of each orbiter). White tiles rarely become available for sale. RR Auction COA.
